EinScan Pro 2X 2020 Vs. Photogrammetry

March 08, 2022

 

How does the EinScan Pro 2x 2020 Compare to Photogrammetry?

If you are used to the photogrammetry workflow (taking multiple still images and using software to "stitch" all of the images together to create a 3D object), you will find the EinScan Pro 2X 2020's Fixed mode to be a godsend in terms of speed, predictability and workflow.

Photogrammetry (while able to produce decent results with just software and any camera available) still has a few flaws. There are many variables which can affect the accuracy of your scan including camera lens distortion, settings, lighting and shadows. With the EinScan Pro 2X 2020, everything is self contained within the unit. It projects it's own light and allows for the use of HDR mode to vastly simplify the setup and repeatability of your scans.

The primary limitation of Photogrammetry is the gargantuan task of organizing pictures and letting the computer "process" the information. You never know if the triangulation process will result in good data until you've spent the hours (sometimes even days) to process the pictures. You could have spent hours taking the pictures, and days processing only to find out that the scan was inadequate, setting you back to square one. The EinScan Pro 2X 2020 was designed to solve these issues of unpredictability and high processing times.

 

From the very first scan, each "snapshot" will provide you with instant 3D data feedback so you can evaluate on the spot if the data is good. This leads to a much more predictable workflow where you're simply adding point cloud data with each scan until your object is complete. No guess work involved.

Workflow-wise, Fixed scan mode is similar, and yet superior to photogrammetry in every way. You can utilize different setup options, with an optional tripod (see Industrial Pack) and turn table. The turntable automatically turns the object and the scanner takes a 3D snapshot until you have a full 360 degrees. All automated with just the touch of a button.

How does the EinScan Pro 2X 2020 Handle Meshing?

Once you are happy with the point cloud data generated by the scanner, you can delete the points you don't need by using the intuitive lasso tool within the EinScan Software. You can then process the point cloud into a water-tight mesh. Everything is automated with custom controls producing usable high resolution meshes with ease and predictability. Additionally, if you would like to add colour to your scans (To facilitate use within a CGI/VR/AR/Animation environment), check out the EinScan Colour Pack Add-On.
